I though many of you would like some reference pictures inside the case of a Seamaster Professional 300 quartz model 2541800 aka original James Bond.. Movement cal:1538. I replace all my own batteries and have a very good case wrench. I do not advise anyone that doesn't know what their doing to open the case of a Omega. It is a very simple procedure but you may inadvertently damage the seal.
Inside the lid:
This is the first thing you will see when opening up a Omega Seamaster quartz. It is a anti magnetic protective inner lid for the movement.
This is the cal:1538 movement. Note the 395 battery size. It is reported the Seamaster professional quartz is the toughest Omega model and can with stand 5000g's!
Note the rubber case seal. I inspected mine and it was in very good condition. I used my fingers and removed it and cleaned the seal trough the seal sits in using a q-tip. It wasnt that dirty. I then spray a little silicon on a q-tip and run it around the trough. I clean the gasket seal and apply silicon to the seal using my fingers working it in. This Omega is very similar to my Tag Heuer 4000 other than the Tag does not have the anti magnetic lid inside the case. I have been inside a lot of watches, The Omega Seamaster is a very very well built quartz model. It really is built like a tank. Now that I have seen the inside of the Seamaster, I highly recommend this model for high activities and where shock and vibration is a factor.
